The existing stairs are about 9 7/16 rise, so it will be an improvement, at least, but Id like to try to build them to code. Im pretty sure the run is within code, but not sure about the rise.

While there is some amount of crossover, interior stairs have their own code requirements. Stair Rail System: Residential: Commercial: Handrail Height: 34 to 38 34 to 38 28 with a minimum of 9 clearance between the child and adult handrail 30 to 38 36 to 38 may also serve as guard 34 and 42 34 and 42 Guard Height: 36 minimum 42 minimum: not specified 42 plus or minus 3 36. THe way I calculate that I can fit in a staircase without cutting into the doorway, are as follows: 11 runs at 10' per run. It should be noted that building codes and regulations for exterior stairs are not exactly the same as those for interior stairs. They can be styled in a variety of ways as long as they provide adequate space for a hand to grip them. Rails must be able to support a load of at least 200 pounds and must extend at minimum 12 inches horizontally past the riser nosing at the top of the stairs and at least equal to one tread depth horizontally at the bottom of the stairs. The associated railing height code states that these rails must be placed between 34 and 38 inches above the walking surface of the stairs.

This applies to any staircase with two or more risers. The existing stairs are about 9 7/16 rise, so it will be an improvement, at least, but I'd like to try to build them to code.

I'm pretty sure the run is within code, but not sure about the rise. The top rail must be at least 42 inches in height (В§1910.29 (f) (1) (ii) (B)) and the handrail must be 30 to 38 inches in height (В§1910.29 (f) (1) (i)) (as measured at the leading edge of the stair tread to the top surface of the rail) There are building code requirements for a porch: In the USA, if your porch floor is less than 30 inches. While the finer details will ultimately be influenced by your local government's building regulations, the International Building Code, the International Residential Code and the standards set by the Americans with Disabilities Act of 1990 maintain that exterior stairs that are a required point of egress вЂ“ in other words, stairs that must be crossed on your way in and out of the building вЂ“ must have handrails. THe way I calculate that I can fit in a staircase without cutting into the doorway, are as follows: 11 runs at 10' per run.
